【问题描述】：

我正在使用什么： IntelliJ IDEA 汤姆猫 马文 MySQL

我有一个“工作”项目，它不读取资源文件。我正在尝试将我的样式文件夹添加为 spring-servlet.jsp 中的资源，但是向此文件添加任何标记都会引发此错误：

HTTP Status 500 - Servlet.init() for servlet spring threw exception

type Exception report

message Servlet.init() for servlet spring threw exception

description The server encountered an internal error that prevented it from fulfilling this request.

我今天没能在课堂上跟得上那么多，所以可能有其他设置和我所知道的设置不正确，所以不要害怕在那里提出问题......只是不能保证我会知道答案的。

【问题讨论】：

  • 看起来您忘记关闭 spring-servlet.xml 中的 beans 标签
  • 对不起，我忘了缩进，所以它没有显示在代码标签中。它存在于我的文件中。

标签： java spring hibernate maven tomcat


【解决方案1】：

假设你的spring-servlet.xml 应该这样修改。

<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:mvc="http://www.springframework.org/schema/mvc"
    xmlns:context="http://www.springframework.org/schema/context"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="
        http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/mvc
        http://www.springframework.org/schema/mvc/spring-mvc.xsd
        http://www.springframework.org/schema/context
        http://www.springframework.org/schema/context/spring-context.xsd">


   <bean id="sessionFactory" class="org.springframework.orm.hibernate3.AbstractSessionFactoryBean" abstract="true"/>
<context:component-scan base-package="com.grandcircus.spring" />
<mvc:resources mapping="/styles/**" location="styles" />

</beans>

您可以参考此post 了解更多详情。

【讨论】：

  • 谢谢你，拉吉斯！这已经解决了错误，但是 .css 文件仍然没有通过。除了添加 mvc 资源之外还有什么我应该做的以在 jsp 中读取 .css 吗？
  • css 文件在哪里？如果它们在webapp 内，则上述配置有效。如果它适合你，你也可以接受答案。(+1)
  • 它们在网络应用程序中，但是当我尝试输入它们时，自动更正不会“拾取”并且不会显示 css
  • 它们在 webapp/WEB-INF/styles/main.css
